I don't want to get my hopes up

Sam
Please help me lol. So, my OBGYN said that I have a very low chance of conceiving. My right ovary has monthly cysts and the left on doesn't produce eggs. She said it would take years to get pregnant. So, on a daily basis, due to my cysts I'm normally nauseous on and off, have no appetite, and have right side pelvic pain. My husband and I have been trying to conceive for about 4 months now. Over the past two weeks or so, my nasea has gotten worse, to the point I want to vomit, but don't. I have headaches, moody, my nipples hurt, I'm hungry but don't want to eat, and hornier than normal. Now, I've taken pregnancy tests, and it's too early for it to show on a test. I have 8 days until I'm supposed to start my period. I can't tell if my PMS symptoms are getting worse, or if I'm pregnant. I've tried to get a blood drawn test, but I'm military, and my chain of command said they won't order a blood test until I get a posative pregnancy test. Do y'all think I'm pregnant?
